I have a packet of Spotted Beebalm seed which actually contains two types of seed.

I group-planted both Spotted Beebalm and Lemon Beebalm (separate pots) at the same time. When they sprouted, it was obvious the Spotted Beebalm pot contained two types of seedlings, and by comparing the two pots, it was easy to see which were Beebalm and which were not. I separated nine of the unidentified seedlings into a small cellpack and destroyed the rest, leaving the pot to the Beebalm.

Here are a couple close-ups of the largest seedling, showing the leaves and the stalk, and a (poor) photo of the cellpack they were moved into:

When I first realized there were two types of seedlings, I immediately checked the seed pack to see if the seed themselves were mixed, or if I had inadvertantly sown the beebalm into a pot previously sown with something else.

Here is a photo of some of the seed; the photo quality is poor, but there are clearly two types. There is some chaff, but the beebalm seed look like little beetles, and the unknown seed are rough-surfaced and round.

I'm not expecting a definitive ID, just hoping they look familiar enough I can get a couple SWAGs (super wild-a$$ guesses) to help put me on the right track as I watch them grow.

Any thoughts?

I googled 'daisy seedlings', and a couple of the first photos that came up with just a couple true leaves look very close.

So I googled 'daisy seeds', but none of the seed looked round as in my mystery seed. When I get a chance in a couple days, I'll have to take the jeweler's loupe and get a real close-up view of just how these seed look.

Thanks for the input. There are a =lot= of different daisies out there, so I'm keeping an open mind.

By the way, these were not purchased seed. They were received as part of my incoming seed from the large Hog Wild Swap seed-trading event this past winter, so not commercial seed.

I Googled "Chenopodium seed", then used a 15x jeweler's loupe to compare with my seed. Not only did it appear to be a match, I learned what I was calling a rough-surfaced seed was actually a tiny, shiny black seed covered by a thin seed coat. I took a small pinch of my seed and rubbed hard between my thumb and forefinger and checked again. Sure enough, there they were, the tiny, shiny black seed!

Thanks so much for your help!

Now I can do a focused search as the plants develop to narrow down as to species.

Thanks again!
